NVIDIA graphics partner GALAXY Microsystems is in preparation of a new custom designed GeForce GTX 285 video card with 2 GB of onboard GDDR3 (0.8ns) memory. The tricked out card will feature Arctic Cooling's Accelero EXTREME triple fan heatsink and stock clock speeds that can be changed at any time - 648 MHz core/ 1476 MHz shader/ 2484 MHz memory. The card comes with a digital PWM design whereas the reference design comes with 6 phase analog power. Two BIOS chips are also presented on the blue PCB of the card. It is also compatible with GALAXY's Xtreme Tuner Utility software, that allows users to manipulate things like BIOS recovery, fan speed, and clock settings.

by: newtekie1Their next GPU core GT300 is expected to bring GDDR5 support. In their current cards, it isn't needed.

If it isn't needed now then they might not even use it in the future. Nvidia is known to be improving existing tech rather than jumping into new one. Not only that they rather sticking with a cheaper tech and charges premium for it like GDDR3.
